Musical styles collided when Nas hit the Jazz Room at The General. While the rapper enjoyed an intimate dinner, former Nine Inch Nails drummer Alex Carapetis started jamming onstage. “You could tell [Nas] was getting into it,” said a spy. “He jumped onstage and started freestyling with Alex.” Then “the whole room gathered in front of the stage to get a better view of the impromptu concert . . . [the musicians] fed off each other’s energy and had the crowd cheering.” Nas then headed next door to party at nightclub Finale.
